The conservation status of the world's freshwater molluscs
2021
With the biodiversity crisis continuing unchecked, we need to establish levels and drivers of extinction risk, and reassessments over time, to effectively allocate conservation resources and track progress towards global conservation targets. Given that threat appears particularly high in freshwaters, we assessed the extinction risk of 1428 randomly selected freshwater molluscs using the IUCN Red List Categories and Criteria, as part of the Sampled Red List Index project. We show that close to one-third of species in our sample are estimated to be threatened with extinction, with highest levels of threat in the Nearctic, Palearctic and Australasia and among gastropods. Threat levels were hi…
Limonium albarracinense (Plumbaginaceae), una Nueva Especie para la Flora Ibérica (España)
2018
Se describe una nueva especie de Limonium Mill.: L. albarracinense Pau ex P. P. Ferrer & R. Rosello. (Plumbaginaceae) para los substratos yesososalinos de las localidades de Royuela (Sierra de Albarracin) y Villarquemado (Comunidad de Teruel) en la provincia de Teruel (Espana). Se aporta una lamina y una tabla donde se compara con otros taxones muy proximos morfologicamente.
Common Bottlenose Dolphin Protection and Sustainable Boating: Species Distribution Modeling for Effective Coastal Planning
2020
Indicators for preserving marine biodiversity include knowledge of how the spatial distribution and critical habitats of species overlap with human activities and impacts. Such indicators are key tools for marine spatial planning, a process that identifies and resolves conflicts between human uses and the conservation of marine environments. The common bottlenose dolphin in the Mediterranean Sea is considered a vulnerable species by the IUCN Red List and a priority species of the EU Habitat Directive. Here, we estimated spatio-temporal patterns of the species occurrence in the area around one Marine Protected Area (MPA) and two Sites of Community Importance (SCI) of the North western Sardin…

A case study of the coconut crab Birgus latro on Zanzibar highlights global threats and conservation solutions
2021
Abstract The coconut crab Birgus latro, the largest terrestrial decapod, is under threat in most parts of its geographical range. Its life cycle involves two biomes (restricted terrestrial habitats near the coast, and salt water currents of the tropical Indian and Pacific Oceans). Its dependence on coastal habitat means it is highly vulnerable to the habitat destruction that typically accompanies human population expansion along coastlines. Additionally, it has a slow reproductive rate and can reach large adult body sizes that, together with its slow movement when on land, make it highly susceptible to overharvesting. We studied the distribution and population changes of coconut crabs at 15…
De Novo Genome Assembly of the Raccoon Dog (Nyctereutes Procyonoides)
2021
The raccoon dog, Nyctereutes procyonoides (NCBI Taxonomy ID: 34880, Figure 1a) belongs to the family Canidae, with foxes (genus Vulpes) being their closest relatives (Lindblad-Toh et al., 2005; Sun et al., 2019). Its original distribution in East Asia ranges from south-eastern Siberia to northern Vietnam and the Japanese islands. In the early 20th century, the raccoon dog was introduced into Western Russia for fur breeding and hunting purposes, which led to its widespread establishment in many European countries, Figure 1b. Together with the raccoon (Procyon lotor), it is now listed in Europe as an invasive species of Union concern (Regulation (EU) No. 1143/2014) and member states are requi…
Old sleeping Sicilian beauty: seed germination in the palaeoendemic Petagnaea gussonei (Spreng.) Rauschert (Saniculoideae, Apiaceae).
2015
Petagnaea gussonei (Apiaceae) is a perennial herbaceous species endemic to northeast Sicily (Nebrodi Mountains). It is considered a remnant of the Sicilian Tertiary flora, and is endangered according to the Red List. There is no information in the literature about the germinability of its seeds, even though seed production is know to occur. The aim of this study was to obtain data to better understand seed germination of this species and its biological implications. Thus, several approaches were employed: vitality analyses, gibberellic acid supply, germination and soil microbial flora analyses via end-point and qPCR. The results suggest that seed germination occurs after ca. 1.5 years at a …
IsBattarrea phalloidesreally an endangered species?
2020
Battarrea phalloides (Basidiomycota), a fungus included in many Red Lists worldwide, requires verification of its real conservation status. One of the main problems in the assessment of fungal spec...
Revision of Nymphaea candida range - New DATA on the distribution and habitat preferences of the species in Southern Poland
2011
The paper presents results of geobotanical and taxonomic studies on the distribution and habitat requirements of <em>Nymphaea candida</em> in southern Poland. The researches were conducted in southern Poland in 2003-2009, in the provinces of Lower Silesia, Lublin, Małopolska, Opole, Silesian province as well as, in southern parts of Mazowieckie and Lubuskie. Flowers, leaves and fruits of <em>Nymphaea</em> species were collected from 27 locations. Altogether pollens from 73 populations of <em>N. candida</em> and 18 of <em>N. alba</em> from all the researched area were measured. The trophic level of an ecosystem was evaluated according to the re…
REVISION OF THE MEDITERRANEAN AND SOUTHERN AFRICAN TRIGLOCHIN BULBOSA COMPLEX (JUNCAGINACEAE)
2010
The Triglochin bulbosa complex (Juncaginaceae) from the Mediterranean region and Africa is revised. One new species, Triglochin buchenaui Köcke, Mering & Kadereit, and two new subspecies, Triglochin bulbosa subsp. calcicola Mering, Köcke & Kadereit and Triglochin bulbosa subsp. quarcicola Mering, Köcke & Kadereit, are described from South Africa. The only two Mediterranean taxa in the complex (Triglochin barrelieri, T. laxiflora) are elevated to species rank. Altogether seven species and four subspecies are recognised: Triglochin barrelieri, T. buchenaui, T. bulbosa subsp. bulbosa, T. bulbosa subsp. calcicola, T. bulbosa subsp. quarcicola, T. bulbosa subsp. tenuifolia, T. compac…
